Need for Network Service Providers

Most network service providers wish that their optical network can handle multi-vendor interoperability along with disaggregation of hardware and software platforms. However, optical networks are quite multi-faceted, which involves multiple optical impairments, i.e., optical signal-to-noise ratio, modulation, cross talk and dispersion a�ect which will be cascaded across the multi-vendor optical equipment. Due to this, every vendor will have their own set of algorithms to configure the optical parameters of their set of system components, for a particular optical channel.

The challenge lies in the fact that managing these optical impairments across the multi-vendor equipment requires a standard algorithm to be followed across the optical components. This is possible only when all optical hardware components expose their standard APIs to a common interface module and support standard protocols to exchange configuration and operational parameters.

To address these problems, open, disaggregation and programmability are now finding its way into the world of optical transport networks. This will ensure automation of configuration and operational tasks on disaggregated photonic components, which are complex and analogue in nature.

Network service providers should rapidly advance to manage a blast of computerized tra�c driven by multimedia services, versatile applications, web based life, VoIP, and edge computing. Additionally, there is a continuous growth in usage of bandwidth hungry applications. Earlier, network tra�c was all about voice calls carried over circuit based networks in a predictable environment. But now, being everything getting virtualized and going to cloud, there is a significant need to upgrade optical transport networks. To ensure this transition with minimum cost involvement, an open and flexible architecture with programmability and modularity is the immediate need.

Optical Transport Network – Backbone of Networking

STL is developing pWDM solution to address the optical transport requirements by providing converged platform and integrated approach to provide the multi-service packet services across the optical domain. It significantly improves the control architecture & algorithms, open standard APIs and mix-match transponders/terminals and open line system components.

pWDM is a converged and integrated platform that o�ers control and feedback mechanism for e�ective channel utilisation, signal regeneration and overlapping protections across packet and optical layers. It employs a vendor-neutral ecosystem that uses open interfaces and common data models to provide economies of scale. It significantly improves provider’s business model as it o�ers the ability to launch innovative services with a faster time to market.

With a centralised control, management and automation with coherent integration with 3rd party applications, terminal devices and OLS equipment o�ers e�ortless ease in network management. pWDM is open-source compliant for developing a OpenROADM and OpenConfig-compliant ecosystem with TIP, ONF-ODTN and OpenROADM community together with STL.

pWDM will disaggregate transponders from OLS and will bring value in following ways:

Business Benefits of pWDM:

•••••

It will enable vendors to innovate in terms of speed, reach, QoT, etc. at terminal equipmentIt will simplify operators networking through simple bookendingReduces time to market to launch new services in production networkRealize DevOps model through SDN-enabled optical networkBuild CI/CD pipeline between operator, vendors, and open source software stack

For metro-haul optical transport networks, pWDM provides a converged platform to provision multi-service packet services across the optical transport domain with a control and feedback mechanism for e�ective spectrum utilisation. This ensures greater flexibility and optimal utilisation of resources.

In addition, it allows for faster and simpler launches with an analytics-driven user experience for intelligent business modules. pWDM also ensures faster time-to-market and idea-to-install capabilities to help service providers compete e�ectively in the industry.
